LT1 w/FAST XFI issue

[mastin3137]

Just curious if anyone has any advice on an issue I've recently encountered. My bracket car is an LT1 with FAST XFI and an MSD Opti. My data logs shoe that I have error code2-128, it doesn't come on until 5300-5600 rpm. I have been trying to track down the issue for a week or so with no success. Has anyone else encountered this or have any advice?
